Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus is disclosed for mounting a siphon type converter tap hole pipe onto a tap hole mounting part of a converter vessel.  The apparatus comprises a lower car and an upper car disposed on a ladle car capable of travelling beneath a converter vessel.  The lower car and upper car are capable of travel in the direction of travel of the ladle car and in a direction perpendicular thereto, respectively.   A loading table is mounted on the upper car, which loading table is guided by an upright support frame and is capable of movement upwardly and downwardly with a siphon type converter tap hole pipe loaded on the table.   Bolt tightening and untightening units are provided on the loading table in positions corresponding to the respective bolt hole set positions in the flange of the siphon type converter tap hole pipe.   The bolt tightening and untightening units are capable of receiving mounting bolts.  A TV camera is provided on the upper car, and allows an operator to monitor the tap hole mounting part for remote control of the mounting operation.  The apparatus of the invention results in a significant saving of time, as well as improved worker safety.

Abstract: Abstract HIGH DENSITY VERTICALLY STRUCTURED MEMORY     A dynamic random access memory is provided wherein each cell has a storage capacitor and switching device and a bit/sense line or plate located along a sidewall of a trench formed in a semiconductor substrate.  In a more particular structure of the cell, the trench width defines the length of the switching device, with the storage capacitor and a highly conductive bit/sense line being formed along opposite sidewalls of the trench. In an array of such cells, the highly conductive bit/sense line or plate interconnecting a large number of the cells of the array extends continuously from cell to cell within the trench at a sidewall thereof.  Likewise, the storage capacitors of these many cells have a highly conductive common plate extending continuously within the trench at the opposite sidewall.

Title: Apparatus for control of a wooden article
Inventor: SCHULTZ GERT
IPC: B07C5/342
Filed: 1987-05-28
Granted: 1990-11-27
Abstract: Abstract Optical fibres control the height and curvature on the perpendicular level of a number of articles on a conveyor (15) while the articles traverse a box (16) in which said optical fibres are placed so that the light ray is disturb-ed in response to the height and curvature of the articles and outside the box (16),  the articles are scanned by a camera (11). Both from the box (16) and from the camera (11) measuring data are transferred to a computer (13) evaluating the measurements and deciding whether or not the article is to be discarded when it reaches the grad-ing device (41, 42). In this way a reliable, three-dimen-sional control of the articles is achieved.

Title: Cache storage priority

Granted: 1991-07-23
Abstract: CACHE STORAGE PRIORITY                       ABSTRACT        A  data  processing  machine  includes  an instruction unit that decodes and organizes a flow of instructions  for  processing  data.   In  response  to certain instructions, the instruction unit generates requests  for  storage unit resources.   In addition, results generated in the instruction unit in response to certain instructions are supplied for storage in the  storage  unit.   The  storage  unit  selects  in response to priority logic from competing requests for storage unit resources, including a high speed cache storing data,  and a plurality of storage ports for transferring data from the result register to the high speed  cache.   Each of  the  storage  ports  generates requests  for  access  to  the  high  speed  cache  to transfer the data stored in the respective store ports to the cache.  Storage unit priority is determined in part by predicting the fullness of the storage ports.

Granted: 1992-03-24
Abstract: RETRACTABLE ROLLER SYSTEM FOR CARGO HANDLING ABSTRACT OF THE DISCLOSURE     A retractable roller system for handling cargo has a main channel which is mounted on the floor of a vehicle into which cargo is to be loaded.  A pneumatically actuated bladder is mounted along the bottom of the channel and a roller tray on which a plurality of roller members are rotatably supported is mounted in the channel above the bladder.  Extending outwardly from each of the opposing side walls of the roller tray is a flange member, the flange member of one of the walls being at a lower level therealong than the flange member of the opposing wall.  Extending inwardly from each of the side walls of the main channel is a flange member, the flange member of one of the channel walls being at a lower level therealong than the flange member of the other channel wall.  The roller tray is mounted in the main channel such that the side thereof on which this flange is at a lower level is opposite the side of the channel with the lower level flange with the side of the roller tray and main channel having the higher positioned flanges being opposite each other.  The rollers are raised and lowered by inflating and deflating the bladder.  With the bladder deflated, the roller tray moves downwardly to recess the rollers below the level of a removable cover plate.  In such a lowered position, with the cover plate removed, the roller tray can be readily removed from the channel by sidewise tilting which permits the side flanges of the roller tray to clear the side flanges of the channel.

Abstract: The invention relates to a process for modifying the surface of a semicrystalline polymer which process comprises irradiating at least one surface of a semicrystalline polymer composition with radiation which is absorbed by said composition, controlling the intensity and fluence of said radiation exposure so that semicrystalline polymer on said surface is melted and there is ablation or volatilization of less than 1% by weight of the total weight of the polymer within regions of said polymer which are melted, and allowing said melted polymer to cool at a rate which will form a quasi-amorphous polymeric area on said at least one surface, said quasi-amorphous polymeric area having a thickness of at least 5 nm and a polymeric article comprising a semicrystalline polymer having on at least one surface thereof areas having thicknesses of at least 5 nm of the same polymer in a quasi-amorphous state.  Semicrystalline polymers of the articles thus can have predetermined amounts of their surfaces rendered quasi-amorphous by irradiation.  Polymer surfaces which are so modified can display enhanced ability to accept bonding to other materials.

Abstract: RECOVERY OF THALLIUM            Abstract Molten anhydrous chloride salt comprising  a mixture  of  zinc chloride,  thallous  chloride,  lead  chloride,  lead  oxychloride and lead monoxide is poured into water  to partially dissolve the salt and to disintegrate  the undissolved portion of the salt.  Sulphuric acid is added to the mixture to convert the contained lead to insoluble lead sulphate and to complete the dissolution of the contained zinc.  The mixture is treated with chlorine, to oxidize the contained thallium to soluble thallic ion.  Lead sulphate is removed from the mixture by filtration. The  filtrate  is  treated  with  a  reducing  agent,  preferably sulphur  dioxide or  a soluble  sulphite,  to  convert  dissolved thallium ion  to relatively  insoluble thallous chloride.   The thallous chloride product is filtered off,  washed,  dried and packaged.  The filtrate, containing the zinc originally present in the chloride salt, and a minor proportion of the thallium, is treated to recover the contained thallium.

Title: Elevator system monitoring cold oil
Inventor: SHAH DENIS D
IPC: B66B1/04
Filed: 1988-06-09
Granted: 1990-11-27
Abstract: 53,783 ABSTRACT OF THE DISCLOSURE A hydraulic elevator system for monitoring a cold oil  thermostat mounted on  a hydraulic  oil reservoir to prewarm the oil prior to passenger service by recirculating the oil in the reservoir through a pumping path which goes past      up and down valves, thus bypassing the hydrau-lic  jack.  A control  circuit  including a microprocessor generally controls all car and corridor functions and is photo-coupled to the thermostat for an input signal which interacts with a program module in a random access memory which  is  run  in  sequence  by  the  microprocessor.   The program module provides  a minimum timer phase  for pump motor energization which is short but normally adequate to circulate the oil to standard minimum operating temperature before the sequencing activates a maximum timer phase which is  cumulative  in time  for  continuous  bypassing  until shutdown.  The tiered total timer counting thus prevents overtemperature problems to avoid damage to the pump motor windings  if  the  thermostat  fails  and  also  prevents recycling.
